IMPROVED MOP-HEAD.

Specification forming part of Letters Patent No. 39,305, dated July 21,1863.

To @ZZ whom, it may concern:

Be it known that I, E. D. MURPHY, of Claremont, in the county ofSullivan and Slate of New Hampshire, have invented a new and ImprovedMop-Head; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawngs, forming a part of this specicationgin whichyFigure l represents a plan or top view of my invention. Fig. 2 is alongitudinal vertical section of the saine, the plane of section beingindicated by the line x Fig. 1.

Similar letters of reference in both views indicate corresponding parts.

This invention consists in a mop head provided with points in thecross-bar of the head and in the follower, and with a screw foroperating the follower, said screw being made to step with itssemicircular foot into a semispherical socket in such manner that itallows the follower to adjust itself, it' more rag is on one side thanon the other.

To enable those skilled in the art to make and use my invention, I willproceed to describe its construction and operation with reference to thedrawings.

My mop-head consists of a frame, A, made of wood or metal in theordinary shape of mop heads, and it is provided with a socket, a., toreceive the handle. The lower cross-bar, b, of the frame A is providedon its inner side with points c, and the sides d form the guides for thefollower B. This follower is provided on its under side with points e,fitting between the points c on the cross'bar b. Between these pointsthe rag or yarn is clamped, and said points retain the rag in thecorners and prevent it shifting in either direction. The follower B isforced down toward the crossbar bby means of a screw, C, which isprovided with two wings7 f, by means of which it can be turned in eitherdirection. This screw is tapped into the inner end of the socket oi,the. outer end of which is bored out to receive the handle ofthemop-head. The foot g of this screw is made semicircular, and it isstepped into a semi spherical recess, h, in the upper or inner edgeofthe follower. By turning the screw (l so that it screws up into thesocket a, the follower is allowed to move up away from the cross-bar I,and the rag or yarns can be introduced. After this has beenaccomplished, and when the rag is fastened on the points c, projectingfrom the cross-bar b, the follower is forced down by means of the screwC, and in' case more rag should be on one side than on the other thesemi-spherical socket or recess h will permit the follower to adjustitself, and the rag is firmly retained all the way across. The points cprevent it from drawing away from the corners, and if the follower isforced down by means of the screw (l the rag is firmly clamped betweenthe points c on the cross bar b and the points e on the follower.

This mop-head is firm in its construction, it can be made cheap, it isdurable, and all its parts are so arranged that they cannot easily getout of order.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

A mop-head having in combination a frame, A, with socket a, screw C,with semieircular foot g, fitting in a semi-spherical step, h, infollower B, which is provided with points e, and a cross-bar, b, withpoints c, all as shown and described.v
